<span>Hazards from huge explosive eruptions comprise extensive ash-falls with small glass particles in it, pyroclastic flows (combinations of hot gases and pumice chunks), and immense lahars which are volcanic mud flows which can even include debris. These put people within the area in danger. Nearby properties get damaged as well within a circumference of tens to hundreds of miles away from the volcano. These eruptions can extensively cause a change to the global climate too. Hazards from quiet eruptions include lava flows which contain exploding fires and creating gas clouds which are rich in chlorine where lava pours into the sea. This can cause damage to wildlife and sea creatures.</span>

Explanation:
Answer:
The composition of a water molecule is one of the first chemical compounds we learn—H2O—two hydrogen atoms and one oxygen atom. The atoms connect in a slightly offset or triangular structure, which creates a positive charge on one side of the molecule and a negative charge on the other.
Explanation:
Water is essential to life—we learn this early in our elementary school years. This information is often accompanied by the fact that over 50% of our bodies are made up of water. However, the lesson does not always go on to explain what it is about water that makes it so essential.

The theoretical yield of Carbon dioxide : 0.544 g
<h3>Further explanation</h3>
Given
0.64 g Methane
1.1 g Oxygen gas
Required
The theoretical yield of Carbon dioxide
Solution
Reaction
CH₄ + 2O₂ → CO₂ + 2H₂O.
Find limiting reactant(mol : coefficient)
= mass : MW
= 0.64 : 16
= 0.04
mol : coefficient = 0.04 : 1 = 0.04
= mass : MW
= 1.1 : 32
= 0.034
mol : coefficient = 0.034 : 2 = 0.017
O₂ as a limiting reactant(smaller)
Mol CO₂ based on mol O₂
From equation, mol ratio CO₂ : O₂ = 1 : 2 , so mol CO₂ :
= 1/2 x mol O₂
= 1/2 x 0.034
= 0.017
Mass O₂ :
= 0.017 x 32 g/mol
= 0.544 g
